What happened
The pilot reported that prior to takeoff, he taxied through several puddles of water resulting from melting snow. At that time, the temperature was reported as 25 degrees Fahrenheit. When he landed at Wildwood, the wind was from 290 degrees at 15 knots, gusting to 20 knots, and the temperature was 30 degrees Fahrenheit. He said that when he landed, the tail and right main gear touched down first because he corrected for a slight crosswind. However, when the left main gear touched down, it seemed to be locked. Subsequently, the aircraft flipped over as it slowed down.
The investigation
When the left main gear was checked immediately after the accident, the wheel would not rotate. However, about one hour later, it would rotate. The pilot reported that when the aircraft was turned right side up, about 1/2 cup of water ran out of the wheel cover.
